Epsilon Muscae


Epsilon Muscae (ε Mus) is a red giant star of spectral type M5III in the constellation Musca.〔 Originally a main-sequence star of around 1.5 to 2 solar masses, it has now expanded to 130 times the Sun's diameter and 1800 to 2300 its luminosity.〔 It is a semiregular variable, varying in eight distinct periods ranging from a month to over half a year in length, with the largest amplitude being of almost half a magnitude from the mean of 4.06.〔 It is located around 300 light-years distant,〔 the same distance as the Lower Centaurus Crux subgroup of the Scorpius–Centaurus Association, although it is moving much faster at around 100 km/s and does not share a common origin.
